Abstract
The construction of a fully assembled frame structure is a process that is both complex and intricate.The structural characteristics make the assembly and connection of prefabricated components fundamentally different from traditional cast-in-place construction methods.Many issues encountered during the construction phase are actually due to deficiencies in the design phase.This paper deeply analyzes the construction practices of connection nodes such as beams and columns,main beams and secondary beams within fully assembled frame structures.By discussing practical engineering cases,referencing relevant standards and atlases,and combining work experience,it proposes design considerations based on well-founded evidence and clear viewpoints.These considerations are systematically summarized into four key points for structural layout,eleven key points for connection nodes,and three key points for construction design,comprehensively covering the main content of beam-column connection design in fully assembled frame structures.Moreover,this paper also features a detailed analysis of the advantages and disadvantages of different treatment methods for the same connection node,clarifying the reasons for suggesting certain practices.The aim is to enable technicians working in the field of prefabricated construction to deeply understand the principles and proficiently master key technologies.This will allow them to anticipate and avoid potential problems during the design phase,thereby improving the safety and construction efficiency of prefabricated structures.关键词
